John Ninnemann’s photography, “Archaeoastronomy: Sky Watchers of the Ancient Southwest,” provides a window into the sophisticated culture of the Ancestral Puebloans who once lived on the Colorado Plateau. It’s clear that the people tracked time, creating calendars based on sunrise/moonrise movement of the sun and moon in relation to both natural and human-caused features on the landscape. This knowledge was essential for agriculture as well as for guiding architectural orientation and ceremony. The exhibit documents sky-watching locations in Mesa Verde National Park, Chaco Culture NHP, Chimney Rock, and Yucca House National Monuments.
